چکیده

کاهش رشد رویشی یکی از پیامدهای زوال بذر است که ممکن است، سبب کاهش عملکرد گیاه شود. در این تحقیق، ضمن ارزیابی بنیۀبذر توده‏های مختلف بذر نخود متعلقبه دو تیپ کابلی و دسی، همبستگی صفات مرتبط با بنیۀبذر با درصد و سرعت سبزشدن گیاهچه در مزرعه تعیین گردید. این تحقیق در سال 1391 در قالب دو آزمایش در آزمایشگاه و مزرعه پردیس کشاورزی و منابعطبیعی دانشگاه رازی انجام شد. در آزمایشگاه، تیمارهای مختلف پیریتسریعشده (دما و مدتزمان)، شامل دماهای 41، 43 و 45درجه سانتیگراد و بهمدتزمانهای صفر (شاهد)، 48، 72، 96، 120 و 144ساعت روی 13توده نخود اعمال شد. در مزرعه نیز 13 توده بذر مختلف نخود در قالب طرح بلوکهای کامل تصادفی با چهارتکرار کشت شدند. تجزیه واریانس دادهها در آزمایشگاه نشانداد که تمامی اثرات ساده و متقابل مربوط به تیمارهای تودهبذر و سطوح پیری بر روی کلیه صفات اندازهگیریشده، بهجز کارآیی استفاده از ذخایر بذر معنیدار بود. هم‌چنین سطوح مختلف پیریتسریعشده تأثیر معنیداری بر خصوصیات جوانه‌زنی نخود داشت، بهطوریکه با افزایش دما و مدتزمان پیری خصوصیات جوانه‌زنی بهشدت کاهشیافت. مقایسه میانگین دادهها در آزمایشگاه و مزرعه نشانداد، توده‌های بذر جدید نسبت به قدیم از خصوصیات جوانه‌زنی و بنیۀبذر بالاتری برخوردار بودند. طول ریشهچه و وزن خشک ساقهچه در آزمون پیریتسریعشده تحت دمای 43درجه سانتیگراد بهمدت 72ساعت از همبستگی بالاتری با هر دو ویژگی درصد و سرعت سبزشدن گیاهچه در مزرعه برخوردار بودند.

چکیده [English]

Introduction
International Seed Testing Association (ISTA) defined seed vigour as "the sum of those properties of the seed which determine the level of activity and performance of the seed or seed lot during germination and seedling emergence". In any seed lot, losses of seed vigour results in the reduction of the ability of seeds to carry out all the physiological functions that allow them to perform. This process, called physiological ageing, starts before harvest and continues during harvest, processing and storage. Any given seed vigour test must be able to provide a more sensitive index of seed quality than the germination test and provide a consistent ranking of seed lots in terms of their potential performance. It must also be objective, rapid, simple and economically practical, reproducible and interpretable. Internationally, many vigour tests have been proposed such as standard germination test, cold test, electrical conductivity test, hiltner test, tetrazolium test, controlled deterioration test, accelerated aging test, etc. The accelerated aging test provides valuable information on storage and seedling field emergence po tentials. In the accelerated aging test, seeds are hydrated to a specific level when ex posed to relatively high temperature (40 to 45 oC) and humidity (around 100 % relative Humidity). Following this aging treatment, seeds are subjected to a germination test and higher vigor seed lots tolerate this aging condition better than lower vigor seed lots and produce a higher percentage of normal seedlings. In this study, chickpea seed lots were exposed to different temperatures and durations in order to calibration of accelerated aging test to predict the seedling emergence under field conditions.

Materials and Methods
This research was conducted as two laboratory and field tests at Campus of Agriculture and Natural Resources, Razi University, Kermanshah, Iran, in 2012. In the laboratory test, accelerated aging treatments (temperature and duration) including 41, 43, and 45 oC and duration 0 (control), 48, 72, 96, 120, and 144 h were performed on 13 chickpea seed lots. Following this aging treatment, seeds were subjected to standard germination test and different traits (including final germination percentage, mean daily germination, daily germination speed, germination rate, germination index, seedling vigor index, and efficiency of seed storage usage) were evaluated. Theses 13 seed lots belonged to both kabloli (Hashem, Azad, ILC-482, Bivanij, Arman cultivars) and desi (Kaka and Pirooz cultivars) types. In the field tests, these 13 chickpea seed lots were planted as a randomized complete block design with four replications. In field test, different seedling traits (including final emergence percentage, mean time to emergence, mean daily emergence, daily emergence speed, emergence rate, and field emergency index) were evaluated. Finally, correlation of different traits related to seed vigor in the laboratory test was determined with percentage and rate of seedling emergence in the field.

Results and Discussion
Analysis of variance in the laboratory test showed that the effects of seed lots, accelerated aging treatments and their interaction were significant on all above mentioned traits except for efficiency of seed storage usage. Different levels of accelerated aging treatments had significant effects on germination characteristics, so that germination characteristics were decreased with increasing of temperature and duration in accelerated aging test. In the field test, chickpea seed lots were different significantly in most seedling traits. Means comparison of laboratory and field experiments showed that the new seed lots had higher germination and vigor characteristics than the old seed lots. Correlation analysis showed that, shoot dry weight in the accelerated aging test under 43 oC , 48 h and root length under 43 oC, 72 h had the highest correlation with seedling emergence percentage in the field test. Root length under 41 oC, 72 h and shoot dry weight under 43 oC, 72 h had the highest correlation with seedling emergence rate in the field test, too.

Conclusion
It seems that accelerated aging test is recommendable to predict the seedling emergence of chickpea in field conditions. The accelerated aging test under 41 oC, 72 h and 43 oC, 48 h had the highest correlation with both percentage and rate of seedling emergence in the field test.
